본 연구의 목적은 arbutine과 유용성감초추출물 혼합물의 미백 효과를 조사하는 것이다. B16 melanoma 세포에서 알부틴 및 유용성 감초 추출물의 tyrosinase 활성과 멜라닌 생성 억제 효과를 시험관내에서 평가하여 미백 효과를 측정 하였다. B16 흑색 종 세포를 이용한 MTT 분석은 혼합물 (알부틴과 유용성감초추출물)이 세포독성이 없음을 확인하였다. 유용성 감초 추출물과 알부틴은 모두 mushroom tyrosinase 활성이 농도 의존적 효과를 보였다. 혼합물은 다양한 농도 (유용성감초추출물 : 알부틴 = 1 : 1, 1 : 1.5, 1 : 2, 1 : 2.5, 1 : 5)에서 B16 melanoma 세포에서 40-51 %의 tyrosinase 활성을 유의하게 억제하였다. 또한, 시험한 모든 혼합물은 B16 melanoma cell의 멜라닌 함량을 50 % 이상 감소시켰다. 이러한 결과는 알부틴과 유용성감초추출물 혼합사용 시 미백 활성에 효과적임을 시사하는 바이다. The aim of this study was to investigate whitening effect of combination between arbutine and oil soluble licorice extract. Inhibitory effects of arbutin and oil soluble licorice extract against tyrosinase activity and melanogenesis in B16 melanoma cells were assessed in vitro to determine whitening effect. MTT assay with B16 melanoma cells showed that mixture (arbutin and oil soluble) was not each concentration. Both oil soluble licorice extract and arbutin induced dose-dependent inhibition of mushroom tyrosinase activity. Various concentrations (oil soluble extract : arbutin = 1:1. 1:1.5, 1:2, 1:2.5, 1:5) of mixtures also significantly inhibited tyrosinase activity in B16 melanoma cells by 40-51%. In addition, the mixtures reduced the melanin contents of B16 melanoma cells by more than 50% at each concentration. These results suggest that mixtures of arbutin and oil soluble licorice extract are very effective whitening ingredients.

카본 블랙은 매우 낮은 밀도로 화장품에는 사용되지 않고 있지만 독성이 없고 안정한 물리적 특성과 검은색의 특성으로 이용 가치가 있다고 사료되는 바이다. 본 연구에서는 TEOS, a) PEO/ lecithin, b) PEO/polyethylene glycol, c) lecithin/polyethylene을 ethanol/water 수용액상에서 계면활성제를 탄화시켜 sol-gei반응에 의해 meso-porous silica샘플을 얻었고 N2 조건하 50℃에서 열처리된 organic-inorganic hybrid silica를 합성하였다. Pore안에 카본 블랙을 함유하는 meso-porous silica는 친수성, 소수성 용매에서 모두 좋은 분산성을 보여준다. 이 샘플은 BET에 의해 specific surface area (750 ㎡/g)과 pore size (4~6 nm)이고, XRD측정으로 pore structure (cylindrical type)를, 샘플의 SEM촬영으로 morphology(0.1~0.5 ㎛ 입자 크기를 갖는 spherical powder)를 갖는다는 것을 알아냈다. 이렇게 합성한 카본-실리카 블랙 컬러를 마스카라에 적용하면 일반적으로 마스카라에 사용되던 블랙 컬러 사용시 보다 좀더 검은색을 보여주는 것은 물론이고 우수한 분산성도 갖는다. 무엇보다 이 파우더의 밀도 조절이 가능하여 마스카라 뿐 만 아니라 모든 화장품에의 사용이 가능하다. Carbon black have not been used as pigment material in cosmetic because of very low density and dispersity, but carbon black have applicable character as black pigment because of non-toxic, stable physico-chemical property, and black colority. In this study, mesoporous silica samples were synthesized by sol-gel reaction using surfactants-template method; TEOS (tetraethoxysilane) - a) PEO/lecithin, b) PEO/polyethylene glycol, c) lecithin/polyethylene glycol in ethanol/water solution. Synthesized organic-inorganic hybrid - silica were heat-treated in N2 condition at 500℃. Mesoporous silica with black carbon in pore have the effective density and show the good dispersity in both hydrophilic and hydrophobic solvent. Properties of the samples were measured; specific surface area (750 ㎡/g) and pore size (4~6 nm) using BET, pore structure (cylindrical type) using XRD, morphology (spherical powder with 0.1~0.5 ㎛ partical size) of the samples using SEM. Carbon-silica black color applied to mascara, it shows a dark black colority and good dispersity as compared with the general black color titania pigment. Moreover, it is possible to control the density of black color pigment because it is possible to control pore volume and particle size of mesoporous silica properly. It show the good volume effects in mascara. That is why possible to apply all kinds of cosmetic products.

This study examined the influences of parent-child conflict and conflict resolution on behavior problems experienced in early adolescence by both boys and girls, and investigated whether conflict resolution had any moderating effects upon the relation between parent-child conflict and these behavior problems. The participants of this study were 397 first and second graders (193 boys and 204 girls) from three middle schools located in Seoul and Gyoung-gi province. To measure the research variables, the Korean-Youth Self Report by Oh et al. (2010), the short version of Conflict Behavior Questionnaire (Homes, 2012), and the Thomas Kilman Conflict Mode Instrument (Cha & Cheon, 2011) were used. The data were analyzed by means of descriptive statistics, t-test, multiple regression analysis, and hierarchical regression analysis. The results indicated that both for boys and girls, the level of parent-child conflict increased the levels of both externalizing and internalizing behavior problems whereas conflict resolution had no significant effect on behavior problems. In addition, in the case of boys only, conflict resolution moderated the effect of father-child conflict on internalizing behavior problems.
